A shoutout to my friend “Walid Khoury”:__ for going out to Nevada to do some canvassing in Washoe County—the results of his work are a big deal. Nevada is going to be huge this year, and now Walid has a stake in it.

Going out to Minnesota in 2006 for Sen. Amy Klobuchar was one of the best things I ever did. It left me with a lasting investment in American politics, and I know I wouldn’t have the job I have now without it. If anybody is thinking of doing any GOTV work or canvassing work, but is on the fence, or doesn’t know what it really entails, or doesn’t know how to sign up to do it, talk to me and I’m sure I can help you out.

Debating 101

1. If you're going to have a discussion, political or otherwise, be prepared to defend or at least explain your assertions.
   
2. Assume nobody but you agrees a priori with your assertions.
3. Familiarize yourself with the list of logical fallacies and how to identify them. Not just to point them out in others but also to spot them in your own arguments.
4. Try not to get defensive.
5. Try not to turn arguments personal. Insulting someone doesn't make them wrong.
6. If you don't understand what someone has said, ask them what they mean. Don't make assumptions since you'll likely be wrong.
7. Repeating an unsupported assertion does not make it true.
8. If you find the debate has gone full circle and you're recovering the same ground as before, then agree to disagree and be done.

Rails Summit: é amanhã, preparem-se!

Estamos próximos! O Rails Summit Latin America começa amanhã, dia 15! Quem deixou para se inscrever de última hora ainda pode participar, mas terá que comprar o ingresso amanhã no local mesmo.

Como eu disse no post anterior tivemos alguns contratempos mas nada que prejudique o evento, apenas tivemos que fazer algumas mudanças na programação. Para ter a programação mais atualizada, acessem o site do evento.

Alguns dos palestrantes eu já soube que estão no Brasil. Falei ontem com o Obie Fernandez, com o Dr. Nic, o George Malamidis, o Danilo Sato. Não falei diretamente mas pelo menos o hotel me informou que o pessoal da Phusion já chegou. Hoje pela manhã o Chad Fowler, o Chris Wanstrath e os outros devem ter chegado também.

Importante: No primeiro dia, logo depois da abertura do Chad Fowler, teremos uma sessão de Q&A (perguntas e respostas) via vídeo online com o David Heinemeir Hansson. Em vez de ser uma palestra, ele prefere uma sessão mais interativa. Portanto, deixem suas perguntas já engatilhadas para fazer a ele. Essa sessão será às 11:20 do primeiro dia.

Alguns me perguntaram sobre o que eu vou falar. Para garantir que ninguém ficará perdido no assunto, farei uma introdução ao Ruby e ao Rails. Será algo parecido com as palestras que venho conduzindo nessas últimas semanas em faculdades. Dessa forma o pessoal terá o básico para continuar nas outras palestras. Aqui vai um sneak preview:

Nos vemos lá!

Careful who you send mail to from staging environment

I’ll often clone the db from production to staging to reproduce bugs or performance issues. The staging site is not visible to the public, so emails with links to it will confuse/annoy people. Today I accidentally sent emails to people from our staging setup.

To stop this happening again – I’ve a quick monkeypatch to only send emails to recipients in our domain. I placed this in config/environments/staging.rb.

class ActionMailer::Base
  def perform_deliveries
    @mail.header['to'].to_s =~ /@example.com$/
  end
end

Replace example.com with your particular domain

Importation de données YAML problème d'import

Lorsque j'utilise l'importation d'un fichier yml :
rake db:fixtures:load

avec mon fichier yml :

admin:
id: 1
login: admin
hashed_password: c093739843181d80b35a84b1435a3f859d971b83
salt: 62002.5159940098894585
nom: TOTO
prenom: Titi


L'import se passe bien (sans erreurs) mais le champ hashed_password ne semble pas correctement importé. En apparence il semble identique quand le le consulte via phpmyadmin mais il faut que je le retape complètement pour qu'il soit correct, il en est de même pour le champ salt.
Ca fait comme si il ajoutait \\n à la fin

J'ai essayé le code suivant qui ne fonctionne pas non plus :

hashed_password:
salt:


Je suis obligé ensuite appeler une fonction pour corriger :

Oh please let me go back to Windows, please!

"But there's also productivity value that you get on Windows Vista that you can't get on a Mac. You can't get Outlook, you can't get Visio, you can't get Project. And when you do get applications such as that, they're usually stripped-down versions that don't have nearly the amount of features, or the usability like the ribbon on Office. Those types of things just don't come with a Mac. And that you don't get the best in terms of hardware experiences, you don't get high-definition playback on Blu-ray DVD on a Mac. You can't do it, can't get it, it's just not there." -- [Brad Brooks, vice president of Windows Consumer Product Marketing via cnet news]

A Helper for Testing Access Control with RSpec

Rails Time Travel Revisited: Manipulating Time.now for Specs

1. Copy the following code into spec/time_spec_helper.rb
   

   
   unless Time.respond_to? :real_now   # prevent the error: stack level too deep (SystemStackError)
   # <b>Test Helper: used only in testing!</b>
   #
   # Extend the  Time  class so that we can offset the time that  now
   # returns. This should allow us to effectively time warp for functional
   # tests that require limits per hour, what not.
   #
   # Example usage:
   #   require File.expand_path(File.dirname(__FILE__)   '/../spec_helper')
   #   require File.expand_path(File.dirname(__FILE__)   '/../time_spec_helper')
   #
   #   describe YourModel do
   # 
   #     before(:each) do
   #       pretend_now_is(Time.local(1999, 8, 1))  # position *all* tests back in time!
   #     end
   # 
   #     after(:each) do
   #       Time.reset    # jump back to the present
   #     end
   #
   #     it "should be 1999" do
   #       Time.now.year.should == 1999
   #     end
   #
   #     # If one particular spec needs some time jumping of its own...
   #     it "should jump to decades" do
   #       pretend_now_is(Time.local(1960)) do
   #         Time.now.year.should == 1960
   #       end
   #
   #       pretend_now_is(Time.local(1970)) do
   #         Time.now.year.should == 1970
   #       end
   #     end
   #     # ...
   #   end
   #
   #
   # <em><tt>(see reference http://snippets.dzone.com/posts/show/1738)</tt></em>
   class Time
     class <<self
       attr_reader :offset
       alias_method :real_now, :now
       def now
         @offset = 0 if @offset.nil?
         real_now - @offset
       end
       alias_method :new, :now
   
       # Warp to an absolute  time  in the past or future, making sure it takes
       # the present as the reference starting point when making the jump.
       def set(time)
         reset
         @offset = now - time
       end
   
       # Jump back to present.
       def reset
         @offset = 0
       end
     end
   end
   end
     
   # Time warp to the specified  time . If given a block, it applies only for the
   # duration of the passed block.
   def pretend_now_is(time)
   Time.set(time)
   if block_given?
     begin
       yield
     ensure
       Time.reset
     end
   end
   end

2. Require it in your spec:
   

   
   require File.expand_path(File.dirname(__FILE__) + '/../time_spec_helper')

3. Travel through time in your specs:
   

   before(:each) do
     pretend_now_is(Time.local(1999, 8, 1))  # position *all* tests back in time!
   end
   
   after(:each) do
     Time.reset    # jump back to the present
   end
   
   it "should be 1999" do
     Time.now.year.should == 1999
   end
   
   # If one particular spec needs some time jumping of its own...
   it "should jump to decades" do
     pretend_now_is(Time.local(1960)) do
       Time.now.year.should == 1960
     end
   
     pretend_now_is(Time.local(1970)) do
       Time.now.year.should == 1970
     end
   end

4. Enjoy.

Printing multiple pages on one page with Evince - Linux PDF tools

Right now there seems to be a bug in evince, that doesn’t allow the correct printing of multiple pages per sheet in evince.

I have a PDF containing single sites in landscape format.

The result I expected are sheets like this:

1…3

2…4

However, the result I’m getting, however I mix parameters is:

2…4

1…3

Solution

I used two handy little tools to solve this, the first thing I had to do is merge some single PDF Documents, then create a PDF with multiple pages per sheet.

PDFtk

From the man page:

.bq If PDF is electronic paper, then pdftk is an electronic staple-remover, hole-punch, binder, secret-decoder-ring, and X-Ray-glasses. Pdftk is a simple tool for doing every‐day things with PDF documents.

PDFtk helps us with the following features:

• Merge PDF Documents
• Split PDF Pages into a New Document
• Decrypt Input as Necessary (Password Required)
• Encrypt Output as Desired
• Fill PDF Forms with FDF Data and/or Flatten Forms
• Apply a Background Watermark
• Report on PDF Metrics such as Metadata, Bookmarks, and Page Labels
• Update PDF Metadata
• Attach Files to PDF Pages or the PDF Document
• Unpack PDF Attachments
• Burst a PDF Document into Single Pages
• Uncompress and Re-Compress Page Streams
• Repair Corrupted PDF (Where Possible)

PDFJam

PDFJam is a collection of scripts:

• pdfnup puts multiple document pages together on one physical page at a reduced size
• pdfjoin concatenate multiple PDFs
• pdf90 rotate PDF pages

Solution

As you can see, to merge PDFs you can either use PDFtk or pdfjoin. Here is the PDFtk way:

pdftk 1.pdf 2.pdf 3.pdf cat output 123.pdf

To get a PDF with multiple pages per physical page, we use pdfnup like this:

pdfnup --nup 2x2 --column true joined.pdf
